UNITED STATES PATENT OFFICE HENRY SCHREINER, OF PHILADELPHIA, PENNSYLVANIA.

IMPRVEMENT IN RAILWAY-CARS.

Specification forming part of Letters Patent No. 149,073, dated March 31, 1874; application tiled August 25, 1873.

To all whom it may concern:

Be it known that I, HENRY SOHREINER, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improved Safety Attachment to Railway-Gar Trucks, of which the following is a specication:

This invention has for its object to provide the trucks with a safety attachment to prevent the wheels from leaving the rails by reason of meeting with an obstruction thereon, the result of a collision, a broken axle, or for any other cause and it consists in a pair of hooks suspended from a sleeve on the axlenear each wheel, the lower end of each hook extending under the head of each rail, and kept in place by a truss of crossed bars or levers. The hooks of one side of the truck are connected by a longitudinal bar, as well 'as those of the other side, making with the trusses a rigid frame.

Figure l is a perspective view of a fourwheeled truck fitted wit-h my improved safety attachment. Fig. 2 is an end elevation.

Like letters refer to like parts in both iigures.

In the drawing, A A represent the axles of a four-wheeled truck, upon'which are mounted the wheels B, flanged to run on the rails C. Near each wheel a sleeve, a, is kept in place on the axle by a collar at each side of it. This sleeve has a pendent lug, to which is secured, by a bolt, a curved bar, b, hooked or bent outwardly at its lower end to extend under the head of the rail. -c c are crossed levers, the upper end of each being` bolted to the lug of the sleeve, and its lower end to the opposite hook b, thereby keeping the hooks in position.

during the swaying or vibration of the truck. A rod, d, is bolted at its ends to the hooks b of each side, which rods, with the trusses o, constitute a frame to give greater rigidity to the hooks.

The invention is applicable to existing roads ironed with the ordinary T- rail, necessitating, however, some slight alterations in the switches and frogs; but, where possible, iron of the section shown in Fig. 2 should be used, which can easily be done in building new roads, as this section gives the hooks a greater projection under the head.

So long as the'train is on the track the de- Vice is inoperative; but as soon the wheels rise to leave the rails the hooks engage with the rails, which thus hold them down in place.

IVhat I claim as my invention, and desire to secure by Letters Patent, is

The safety attachment to railway-car trucks, consisting of the sleeves a, curved or hooked bars b, truss-rods o, and side rods d, constructed and combined with the axles, as shown and set forth.

HENRY SGPIREINER.
